The Bafang mid-drive (crank drive) e-motor has long been a very popular choice but the one objection to it has been that it is “unnatural”due to lack of torque sensing. Well, Bafang finally did something about it and now … maybe … it is the best offering out there. (And I just bought a Tongsheng.)

I have a few current blogs (tadpolerider1, navysight, truthtoponder and stevesmixedbag) so I am keeping busy. I hope you the reader will find these blogs interesting and enjoy your time here. Feel free to email me at tadpolerider2 at gmail dot com (


  1. If first impressions mean anything I certainly don’t love it. I am very disappointed with it. It is extremely underpowered. I don’t know if I have everything set up properly. I spin out at about 15 mph and my top speed is about 15 mph. With my hub motor setup I spin out at about 23 mph and my top speed is about 30 mph. I always heard that the Bafang is a real powerful unit … a brute. Well, I am stuck with my choice. I am glad that I still have my hub motor installed as I use it to assist this underpowered Tongsheng. One thing I am impressed with is the fact that it takes so very little battery power to operate. The charge level indicator didn’t drop any at all thruout my ride today. I am not used to that.

  2. Steve, don’t beat yourself up because you bought the Tongsheng unit. You will love it. I put one on my Catrike Road a few months ago and it works wonderfully. I did opt for the bronze gear and it does make a bit louder noise than I like, but it probably will wear in in time (my hearing aids pick up everything). It was a very easy install and comes standard with a 42 tooth crank. I find it’s the perfect crank for my optimum spinning rpm. I was thinking of getting an optional 52 but my wife wouldn’t be able to keep up with me anyway if I did that. We move along at a respectable 12-16 mph. She refuses to get any E assistance yet as she has very strong legs and likes the workout. I usually ride on the #1 setting unless the slope gets too steep. Never much higher than #3. I set it on zero on the flats or downhills. We’ve got some pretty steep ones out here in Scottsdale and I can actually coast down them and hit 35 mph. Thrilling! Also, it looks like the Bafang is $200 higher than the Tongsheng.
    Enjoy the ride!
